CL continues its long standing orbit of 56. For daytrades buying pullbacks during upward trends is probably going to be a good strategy.
Previous uptrends back to 56 have been a bit choppy so looking to buy double bottoms that re-test the low of the day might also be a good intraday strategy.
I would not be buying the high of the day unless it's a very specific case like a high volume 1 minute opening breakout.
